PIVOT-STAND FOR MOBILE ARTILLERY.

T0 all 'whom it may concern Be it known that we, WALTER llenas-MANN and Hnmiucrf KANONENBERG, residing et l lssen-ontheRuhr, Germany, both subiects ot the Emperor of Germany, have invented a Certain new and useful Improvement in Pivot-Stmicls for Mobile Artillery. of which the following is a specification.

The present invention relates to pivot; standsfor mobile` artillery which are nrrnnged in Such a manner that the gun cnrriage proper may he easily and (prickly swung' when a deep groove or trench prrr vided for the trail end of the gun carriage. for the purpose of giving to the gun 4 riage a higher elevation than that for which the carriage has been conetrnetoti.

In the :iceoinl'aanyingj drawing one einhodiment o t' the invention has been illustrated: and i "i;1ire l ehovisasie View partly in .tion of e gun on a. pivot stand; Fig. 2 a similar VView lo Fig'. l, but with dill'erent relative Wisition of the details; and Fig. Il a detail in section and in larger scale.

"the pivot stand luis zi hase A, and a top portion ooneisting of two parte, namely a 'pivot l n lop marriage B1. the former being provided with a trunnion lf2 around 'lle axis of which the top oortion B1 is mounted to be turned relative to the brise 'the top carriage llt provided with boarinrs Rilland bt tor the axle-tree G of the gun Carriage, and is mounted on the pivot B in 4sur-h a manner that it may be displaced in the lonfritudinal direction oi tin: gun earrialge when the latter rests on the pivot Stand. To connect the pivot stand with the gun carriage is provided a ring- R mounted i1; n groove a3 on the brise A. and Vtoritshaped rod E hinged to journals r* of this ring, with Y. rod connects with the trail body F of the gun Carriage by ine-ins of an eyelet. 6'* and a hook f1.

n an upward projection 12 of the ring; R. is hinged an accumulator M, M1, N. eee particularly Fig. 3. This nccnn'iulator f-oiiezisl of two sleeves: M, 'M relutiyely sildnllo to against both of these eleei'os. The in Ye M is hinged to the proitrtion fr'J of the ring ll. oy menneA of a bolt r3, the axis o'f nhirh parallel to the axis of the jouilv nale ri. '.lhe outer M carries a hull joint fm2 'which is intended to eminent, with @erh other und :i Snin" N abut-4 a socket f2 provided on the underside of the trail body F, see Fig.

.ls will he evident from 'the drawing the gun carriage consists of the nenni parte found in mobile artillery; its trail end reSts on level ground with the normal trail pres sure.

Un drawing the glux carriage on to the pivot stand, the trail end is raised hy means of the hund Spillo K, and the accumulator M, M1, N swung from the trnnsportat' n prsition. indicated by dot and dash lines, Vig. 1 into the position in which the bull joint m2 may enter into engagement; with the socket f2 of the trail body. It now the. trail end is laid down on the ground t gag-ement will take place. und the sleeve Ml will thereupon slide down on thev sleeve .Nl compressing the spring N.

Then the gun Carriage is to be swung around` the trail 0nd has to he raised. displacement of the top carriage ll of the pivot Stand relative to the pivot Vll will then take place. so that ther pivot Staind need notI he tilted. The spring' N expands simultaneoiwly, whereby the swingingA of the. gun eurriago will he l'avilitnted ln the turning inovmnent ol' the gun car'iug'e, tho upper part ll B1, the ring' R, the rod E und the noA rnnnilator M, M1, N of the pivot Stand pain take.

The above related nrtion-of the accumulator in particularly advantageous when the trail rnd is laid down into :i groove or trench in the ground Vfor the purpoue oi' gir ing); n greater elevution to the gun Carriage than that for which the Carriage is Constructed The center ot gravity of the gun euri-ingo will then take such a position relative to file :ixlelree (l that the trail ond will rest. with Conniderably Lrenter pressure on the` ground than in the position illus trut il in Fig. l.

We claim:

l. pivot. stand for mobile artillery having n trail7 comprising a base sind a top porti-ini mounted to revolve on said base, .Said top portion being constructed to enqngge with :ind Support. the forfvard end ot the gun rarriago; :ind un accumulator between the of the pivot Stand and the unil of tliegnn carriage, said aorinnulator lining adapted to be strained by the Weight, of the trail end.

i trail of the gun carriage and said base, and

a hinged connection between the trail and said base, whereby said top carriage will be horizontally displaced relative to said base a distance corresponding to the position of the trail end relatively to the ground when moved in a vertical direction.

3. A pivot stand for mobile artillery having a top carriage and a base, said top carriage being constructed to engage with and support the forward end of the gun carriage and being displaceable relatively to said base in the longitudinalV direction of the gun carriage, a resilient member on said base for partially sustaining the weight of the gun carriage, and a hinged connection between the trail and said base, said hinged connection comprising a ring revoluble around said base, a pair of horizontal trunnions on said ring and a fork mounted to oscillate on said trunnions connecting them with said trail; whereby said top carriage will be displaced horizontally relative to said base a distance corresponding to the position of the trail end relative to the ground when moved in a vertical direction.

4. A pivot stand for mobile artillery having a top carriage and a base, said top carriage forming bearings for the axle of the gun carriage and bein displaceable relatively to said base in t e longitudinal direction of the gun carriage, and a hinged connection between t-he trail and said base, said hinged connection comprising a ring revoluble around said base, a pair of horizontal" trunnions on said ring and a fork mounted to oscillate on said trunnions connecting them with said trail; a projection on said ring, a power brake hinged to said projection, a ball and socket bearing between said brake and said trail, said brake being compressed by the weight of the trail end; whereby said top carriage will be horizontally displaced relative to said base adistance corresponding to the position of the trail end relative to the ground when moved in a vertical direction.

The foregoing specification signed at Barmen, Germany, this 23rd day of June, i913.
